10MHz Low Noise/Low G-Sensitivity OCXO
NA-10M-6800 series
NA-10M-6800 Series in 25.4x25.4mm DIP package
NA-10M-6800 series is a 10.000 MHz high performance (VC)OCXO with
low phase noise(LPN) and low G sensitivity(LGS). It has excellent temperature versus
frequency stability with many available options. The part is housed in a hermetically
sealed RoHS package which protects it from extreme changes in external humidity and
pressure.
